Table 2 (Left) Percentages of the five fractions obtained in the Tessier sequential extraction results; EX (exchangeable), CB (carbonate bound), OX (Fe/Mn oxides bound), OM (organic matter bound), and immobile fraction (residue), (Right) percentages of inorganic vs. organic mercury in the samples studied
